I just googled the toilet planters 🚽 I don't understand how there are people in this world who like such stuff.
I dunno if it's the same for you, but for me, the biggest fear is that I might end up having a confrontation with the people I am taking pictures of. Maybe a longer 150mm + lens could solve this problem?
I don't know if it's the confrontation I fear, but maybe just the awkwardness of it.
Depending on the situation a longer lens could be helpful but that also intimidates people more. Usually no body says a thing to me when I am walking around with my phone but my dslr draws attention.
